In their study of online product experience, Jiang and Benbasat (2005) have used the construct perceived diagnosticity to represent consumers’ perceptions of the ability of a website to convey relevant product information that can assist them in understanding and evaluating the quality and performance of products sold online. In the context of online product evaluation, perceived diagnosticity represents consumers’ cognitive belief that a website facilitates their product understanding (Jiang and Benbasat 2005). Higher perceived diagnosticity means that consumers are more capable of understanding products and can make more informed purchase decisions, thus more effectively accomplishing their shopping goals.
